is this right? Provide the correct name for me structure below. include R/S stereochemical intotmation in your name For meso compounds. use the prefix meso in your name (instead of R/9).
Provide the correct name for the structure below. Include R/S stereochemical information in your name for each stereocenter. For meso compounds, use the prefix meso n your name (nstead cf R/S). CI Answer: Check Guidelines for Keeping an Organic Chemistry Notebook tion's Manual Jump to...

Which of the compounds shown below are chiral? (choose all correct) ОН o ОН E Which of the compounds shown below is/are chiral? (choose all correct answers) O For determining whether a stereogenic center is Ror S. the substituents need to be ranked. Rank the following substituents from high to low, entering a 1,2,3, or 4 next to each structure, with 1 for highest priority ranking and 4 for lowest priority ranking. 0-6 -C-H -CH_Br -CH₂OH -c-oh Which of the...
question 4 3) Provide IUPAC names for the following compounds including the correct stereochemical descriptors (i.e. R and S). 4) The pure (R)-enantiomer of compound A has an optical rotation of +100°. Your sample of A has an optical rotation of -50°. What is the %ee of your sample and which enantiomer is more prevalent?
why is the first one S but the second one R? Indicate the stereochemical configuration for the tetrahedral centers shown below. - O OR O not a stereocenter Site 1 Site 1 not a stereocenter Site 2 000 Correct not a stereocenter
7) [28 pts.] L-Proline was recently found to catalytically promote the quantitative stereochemical isomerization of the aldehyde shown below. The proposed mechanism proceeds through the enamine derivative of L-Proline, and involves intramolecular general acid and general base catalyzed steps. Provide the missing structures in boxes 1-4 and arrows where requested. Boxes 2 and 3 are to display different faces of a prochiral double bond, brought about by a conformational change.
